Hi
string conn = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
MySqlConnection con = new MySqlConnection(conn);
MySqlCommand cmd = new MySqlCommand();
cmd.Connection = con;
cmd.CommandText = "Insert_Image";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("?description", SqlDbType.VarChar).Value = txtdesc.Text;
cmd.Parameters.AddWithValue("?fullstr", SqlDbType.VarChar).Value = path;
con.Open();
cmd.ExecuteNonQuery();
cmd.Connection.Close();
Session.RemoveAll();
My code is giving error at executenonquery, "Input string not in correct format". The values in path and txt dec are correct.
Can you please tell where i am wrong?

The AddWithValue method expects the actual value to be passed rather than the data types, so you should write something like:
cmd.Parameters.AddWithValue("?description", txtdesc.Text);

Thanks alot!
I am new to MY SQL database and my problem is solved.

You're welcome.
However, this problem isn't related to My SQL in any way, rather it is to do with ADO.NET.
|
|
|
|
|
When I use MySQL I use an at (@), not a question mark (?) -- I thought that was the problem, does it work with the question mark?
|
|
|
|
|
Dunno, but it works without any mark too. I only use the @-sign within the Sql-statement, the AddWithValue method always without.

Dear all,
I'm new comer in SQL, I have problem in web development, in my system there is searching for phonetic name like nielsen and nelson. Example:
If I enter test word 'nielsen' then output can be 'nilsen','nelson'. I've used sounds like but it given so many return and the return have far distance with test word. Also I have implemented it with traditional way, but the searching running slow, I compare some data (from excel, the number of data 200 record) with database record about 600.000 record.Does anyone have idea with my problem?Or have implement this case? Thank you for helping..

As you haven't said what the database is, I'm going to assume you are talking about SQL Server. Most "real" databases provide a SOUNDEX[^] function which can be used to do this form of matching.

Hi nagy,
Thank you for your answer, I used MY SQL, and I've used soundex, but it return too many result which not match to my keyword, how about you idea bro?
Thank you,
Regards.

Please try out this Code Project Article[^]. It has a total of 6 parts and the current one handles your situation.
Also you can try out with Metaphone approach which performs better that Soundex. Here[^] is an implementation for the same.
Hope that helps

Hi Niladri,
Thank you for your answer.. I want to, can that solution if we want to compare 100 data in table a with 100000 data in table b. so it looks like google search, when program compare 1 data to 1000, the system doesn't compare to all data, but only similar data, and the system give return hit, example: 1 data is suspected similar with 8 data in table b. Can the solution solve the problem niladri?
Thank you,
Regards

Morning all. I need to select certain data from a table:
PI JobID FormID ShiftID StartEvent SW SG End Event EG EW
3 9249 36208 6241 2010-08-14 10:00:15.610 0 0 2010-08-14 10:14:52.000 143 109
3 9249 36208 6241 2010-08-14 10:14:52.217 109 143 2010-08-14 10:15:04.000 150 109
3 9249 36208 6241 2010-08-14 10:15:04.763 109 150 2010-08-14 10:15:07.000 150 109
3 9249 36208 6241 2010-08-14 10:15:09.820 109 150 2010-08-14 10:29:15.000 150 221
3 9249 36208 6241 2010-08-14 10:29:15.570 221 150 2010-08-14 10:53:09.000 376 300
3 9249 36208 6241 2010-08-14 10:53:09.240 300 376 2010-08-14 11:01:18.000 4294 1824
3 9249 36208 6241 2010-08-14 11:01:18.553 1824 4294 2010-08-14 11:02:06.000 4294 1942
3 9249 36208 6241 2010-08-14 11:02:06.363 1942 4294 2010-08-14 11:02:14.000 4294 1920
Out of this I need to get the start values and the end values, ignoring everything in between, essentially reducing it to this:
PI JobID FormID ShiftID StartEvent SW SG End Event EG EW
3 9249 36208 6241 2010-08-14 10:00:15.610 0 0 2010-08-14 11:02:14.000 4294 1920
Any help will be much appreciated.
-edited to show that min and max values on SW, SG, EG, and EW may not necessarily work

Try this ...
select PI,JobID,FormID,ShiftID,Min(StartEvent),Max(End Event)
from someTable
group by PI,JobID,FormID,ShiftID
|
|
|
|
|
Thanks for the reply. That works for the times, but doesn't cover SW, SG, EG, and EW.
|

Here is a fix up on David's query:
select PI,JobID,FormID,ShiftID,min(SW) as SW,min(SG) as SG,max(EG) as EG,
max(EW) as EW,Min(StartEvent) as StartEvent,Max(EndEvent) as EndEvent
from someTable
group by PI,JobID,FormID,ShiftID
Hope this helps out.

Thanks for the reply. That's basically what I have now for my query. Unfortunately min and max only work on the timestamps. I need to select the specific values tied to those timestamps as there might be higher or lower values in the rest of the data. I updated the sample data to reflect that.

I am suspecting you probably need a select subquery to get the last row that you had updated the sample dataset with, because my query doesn't give you the 1920 in the EW column.
The subquery might be one in which you get the minimum timestamp and the maximum timestamp, then the actual main query pulls the other information out of the subquery. essentially, David's query would be the subquery. Just a thought.
You may want to do this as a stored procedure instead.

You're missing the SW, SG, EW, and EG fields he needed
